Digital Home Thoughts: HTML5 and Flash in a Video Cage Match

"Since the comparative efficiency of Flash vs. HTML5 seemed easy enough to quantify, I endeavored to do so, using YouTube's new HTML5-based player as the test bed. Specifically, I played a YouTube video in the same browser twice, once via HTML5, once via Flash, and measured CPU utilization during playback."

The results of Streaming Learning Center's tests shuld not be considered exhaustive but it does indicate that HTML5 is an viable all around solution for streaming video to web browsers that support it. The results also show the huge difference between implementations for the Mac version of Flash compared to Windows. I imagine that Linux tests would more closely emulate the results seen on the Mac compared to Windows as well. It should signal to Adobe that it has a lot of work to do in terms of optimizing Flash for OS X and Linux if it wants to remain relevant in today's web. Unfortunately, while Flash also offers a lot of flexibility to allow designers to create more interactive websites more easily, or to develop games, probably the biggest strike against it is that advertisers currently really favor the format as well. Of course, as HTML5 matures and becomes more universally supported, advertisers will begin to design HTML5 based ads, which may end up becoming a horror story in itself.
